Phase One: 100-50%
Boss Mechanics
He will alternate between his regular mechanics and an underground phase.
Bloodplague Crawler (ant): Add mechanic. Grants a stack of Bloodplague Essence on death.
Bloodplague Essence: Stacking buff. Increases damage each stack. Lasts 50 seconds.
The Bloodplague Crawlers will spawn throughout the entire fight. Managing and maintaining the damage buff by killing them is key to completing the encounter. Maintain this buff all the time.
Above ground
Tail Lash: Back cleave.
Necrotic Breath: 1.5 second cast followed by 6s channel. Frontal cleave mechanic. The tank eats this.
Nerve Damaging Poison: Swap mechanic. Reduces max Hp by 10% per stack. Swap at 4-5 stacks. Damage portion of the same name.
Rampant Decay: Debuff on random player. Drops AOE on the ground.
Seismic Disruption: Knockback. Grugonim burries himself underground and knocks the raid back. Triggers Underground Phase.
Underground Phase
Corrosive Ooze: AOE left behind by Grugonim.
Following Seismic Disruption the boss will go underground and leave a purple AOE trail - Corrosive Ooze - ("lane"). You need to kite him in a straight line to avoid and drop the AOE trail. If you are too close he will do a knockback (and you get damaged by the purple AOE) but if you are too far away he will charge at that player killing everyone behind him. Stack up on the tank and move slowly in a straight line. See below for just one example of how to drop the lanes.
Strategy
The tank needs to face him away from the raid and eat Necrotic Breath. The raid and second tank should stack up on his side. When Rampant Decay hits move through the boss to his other side. Have the inactive tank pick up the ants. Before Seismic Disruption the tanks needs to turn him towards the raid so everyone gets knocked back. Proceed through each underground phase as described above until the boss reaches 50%.

Phase Two: 50%-10%-0%
Boss Mechanics
Upon reaching 50% he will burry himself once again. Four death spires (idols) will spawn around the room.
Manifested Death: Idol. ~20million HP each. Casts Death Beam, Necrotic Immolation and Death Bolt.
Death Beam: Interruptable cast. Deals damage. Interrupt.
Necrotic Immolation: Deals damage 20m around the Manifested Death. Avoid standing too close.
Death Bolt: Deals damage.
Parasite Swarm: AOE debuff on the raid. Reduces max Hp by 4% per stack. Deals damage (Flesh Eating Parasites).
Strategy
Make sure Grugonim is facing away from the raid once this phase starts. He will continue casting Necrotic Breath after he reemerges soon after. Stack up once again and start killing the death spires maintaining interrupts and a safe distance (or move out on Necrotic Immolation). There will be intense AOE damage during this phase. Move from each icon to the next. As soon as the last one dies the boss will be active again. Make sure one of the tanks is ready to pick him up.
He will gain an additional ability and resume his Phase One mechanics (including Underground Phases).
Corrosive Bile: AOE on two players. Move out quickly. Similar to Rampant Decay.
Reaching 10% he will spawn the Manifested Deaths again. Proceed with killing them all to have him become active again. The AOE healing required is especially challenging during this final phase of the fight.
